Example #1

File: sat_api.c Project: Lcch/CS264A

//returns 1 if all the clauses mentioning the variable are subsumed, 0 otherwise
BOOLEAN sat_irrelevant_var(const Var* var) {
  for (c2dSize i = 0; i < sat_var_occurences(var); i++) {
    if (!sat_subsumed_clause(var->clauses[i]))
      return 0;
  }
  return 1;
}

Example #2
